Embodiment Construction

[0009] When the sacroiliac joint dislocation undergoes anterior reduction and fixation, the sacroiliac joint is exposed and reset during the operation, and the "tadpole"-shaped bone plate corresponds to the front of the sacroiliac joint and the top of the pelvic arcuate line, and the sacroiliac joint bone plate is elliptical. The shape of the reduction bone graft hole corresponds to the joint line of the sacroiliac joint, and there is a deep and smooth concave between the fixation holes of the pelvic arcuate reconstruction bone plate, so that the bone plate can be accurately bent, twisted and changed in shape, and the bone set can be adjusted in a small amount. The plate can effectively make up for the small differences in the shape of the bone plate and the bone surface due to individual differences, so that the bone plate and the bone surface fit better. Because the bone plate is a whole with high fixation strength, the screw holes of the bone plate are oval-shaped two-way se...

Abstract

The invention relates to a special-shaped bone fracture plate in front of a sacroiliac joint. The special-shaped bone fracture plate comprises a sacroiliac joint section bone fracture plate for fixing of dislocation of the sacroiliac joint, and a pelvis arcuate line segment bone fracture plate, wherein the sacroiliac joint section bone fracture plate corresponds to the front part of the sacroiliac joint; the pelvis arcuate line segment bone fracture plate corresponds to the upper surface of a pelvis arcuate line; the sacroiliac joint section bone fracture plate is diamond-shaped, an elliptical reset bone grafting hole is formed in the middle of the sacroiliac joint section bone fracture plate along a joint line, and the front inner edge of the sacroiliac joint section bone fracture plate is connected with the pelvis arcuate line segment arc-shaped reconstruction bone fracture plate into a whole to form a tadpole shape. The special-shaped bone fracture plate in front of the sacroiliac joint has the advantages that adaptability is better, and operation wound degree is reduced.

Description

technical field [0001] The invention relates to a bone bone plate for fracture operation treatment, in particular to a special-shaped bone plate in front of the sacroiliac joint. Background technique [0002] Sacroiliac joint dislocation is an unstable pelvic ring injury, which requires open anatomical reduction and effective internal fixation to facilitate the recovery of the pelvic ring and achieve good functional recovery. Bone plates used for internal fixation in surgery require good structure and certain strength to meet the requirements of reduction and internal fixation. At present, the internal fixation of sacroiliac joint dislocation is usually fixed with multiple bone plates separately. When the dislocation of the sacroiliac joint is difficult to reduce and needs to be pulled and reset with bone plate screws, the ordinary bone plate has low strength and is difficult to do. The fixation strength is also low after the dislocation is reduced, and the firmness of the ...
